Earth's lower atmosphere is rising due to climate change, new study says
... to collect data on the tropopause for the past 40 years, an international team of scientists have found that the troposphere (the lowest atmospheric level) has been expanding upward at a rate of roughly 50 to 60 metres per decade. The rising...

Did two ancient supernovas cause cell mutation and climate change on Earth?
...extinction occurred. This may be connected to a cooling in Earths climate, as the increased abundance of cosmic rays ionised Earth’s troposphere – the lowest level of the atmosphere – to a level eight times higher than normal and subsequently causing...

JAXA’s challenge to climate change
... to verify reductions in carbon dioxide (CO2) emissions. A decision was made to change the mission completely in order to monitor tropospheric CO2 absorption and emission. The instrument design was changed for the sole purpose of measuring GHGs...
